CASING SHOES
CSUMXTM
The CSUMXTM casing shoe is designed
for all exploration and geo technical casing applications. The ability to drill faster with high penetration rates and outperform existing shoe technology in a wide range of ground formations makes the CSUMX ideal for anyone seeking a cost-effective alternative to their current shoe selection.
UltramatrixTM
CSUMX impregnated casing shoes feature Boart Longyear’s patented UltramatrixTM formula. Ultramatrix technology enables the use of large synthetic diamonds with an innovative formula, increasing penetration through various ground formations while providing longer shoe life.
This optimization couples the high penetration capability with longer shoe life and allows the CSUMX to cut easily from one ground formation to another.
